The cDNA clone of restrictocin was placed under the control of the glucoamylase promoter from Aspergillus awamori and was transformed into Aspergillus nidulans and Aspergillus niger. Site-specific changes were introduced into cDNA constructs and these were transformed into A. nidulans. The secre...detailed
Restrictocin is a toxin produced by the fungus Aspergillus restrictus. The DNA coding for restrictocin was isolated from the host by polymerase chain reaction and cloned into a T7 promoter-based expression vector. The protein was overproduced in Escherichia coli and remained insoluble in the cel...detailed
Restrictocin, a highly specific ribonuclease produced by Aspergillus restrictus, cleaves a single phosphodiester bond in a universally conserved stem and loop structure termed sarcin/ricin loop within the large ribosomal RNA of all organisms. In the current study, we demonstrate restrictocin to ...detailed
